New template = no css info in there

Hello people,

i want to add a new template to my existing site as my current one is messy.
so i made a regular html page and converted that to a dwt. When i style my existing pages with the new template non of the css styles from previous template are there.

When i have my new template selected none of my css styles from my original site are visible.

How can i copy the style sheet to my new template ?

I'm using dreamweaver cs5 on xp

Any help much appreciated :-)
